The process whereby cells take in liquid material from their external environment; literally 'cell drinking'. Liquid is enclosed in vesicles, formed by invagination of the plasma membrane. These vesicles then move into the cell and pass their contents to endosomes. Any process that modulates the frequency, rate or extent of endocytosis. Any process that stops, prevents or reduces the frequency, rate or extent of a process involved in the formation, arrangement of constituent parts, or disassembly of cell structures, including the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope. Any process that stops, prevents or reduces the frequency, rate or extent of endocytosis. Any process that stops, prevents or reduces the frequency, rate or extent of pinocytosis. Pinocytosis is the process whereby cells take in liquid material from their external environment; literally 'cell drinking'. Liquid is enclosed in vesicles, formed by invagination of the plasma membrane. These vesicles then move into the cell and pass their contents to endosomes. Any process that stops, prevents or reduces the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. Any process that modulates the frequency, rate or extent of pinocytosis. Pinocytosis is the process whereby cells take in liquid material from their external environment; literally 'cell drinking'. Liquid is enclosed in vesicles, formed by invagination of the plasma membrane. These vesicles then move into the cell and pass their contents to endosomes. Any process that stops, prevents or reduces the frequency, rate or extent of the directed movement of substances (such as macromolecules, small molecules, ions) into, out of, within or between cells by means of some external agent such as a transporter or pore. A type of vesicle-mediated transport in which cells take up external materials or membrane constituents by the invagination of small region of the plasma membrane to form a new membrane-bounded vesicle.
